Does it mean you are pregnant if you missed your period have a lot of symptoms of pregnancy but the pregnancy test said no?

If you have missed one period, and the pregnancy test said negative, the 'symptoms' of pregnancy may be mostly psychological. It is possible to miss a period, or to have a late one. Wait another week, try another pregnancy test, and ensure you understand the directions fully. A missed period does not guarantee a pregnancy, but an over the counter pregnancy test does not guarantee the correct answer. Stay calm, wait, and check again. You have lots of time and you have options regardless of whether you're pregnant or not.
